Hi, Is this a server board or a standard motherboard. My Intel server board requires matched pairs of sdram installed in banks 1/2 3/4 and 5/6 respectively as it uses interleaving. If the option exists in the bios, you can try turning off memory interleaving. Even better, try moving the 256mb chip into bank 3 and match the 2 128mb chips into banks 1 and 2.
